    ieee802154: ca8210: Add missing check for kfifo_alloc() in ca8210_probe()
    
    [ Upstream commit 2c87309ea741341c6722efdf1fb3f50dd427c823 ]
    
    ca8210_test_interface_init() returns the result of kfifo_alloc(),
    which can be non-zero in case of an error. The caller, ca8210_probe(),
    should check the return value and do error-handling if it fails.
